WARNING
Don’t Overload Generator
Capacity
You must make sure your generator can supply enough rated (running) and surge (starting) watts for the items you will power at the same time. Follow these simple steps:
1. Select the items you will power at the same time.
2. Total the rated (running) watts of these items. This is the amount of power your generator must
produce to keep your items running. See Figure 10.
3. Estimate how many surge (starting) watts you will need. Surge wattage is the short burst of power needed to start electric motor-driven tools or appliances such as a circular saw or refrigerator.
Because not all motors start at the same time, total surge watts can be estimated by adding only the item(s) with the highest additional surge watts to the total rated watts from step 2.
Example:
Total Rated (Running) Watts = 3075 Highest Additional Surge Watts = 1800 Total Generator Output Required = 4875 Power Management
To prolong the life of your generator and attached devices, it is important to take care when adding electrical loads to your generator. There should be nothing connected to the generator outlets before starting its engine. The correct and safe way to manage generator power is to sequentially add loads as follows:
1. With nothing connected to the generator, start the engine as described in this manual.
2. Plug in and turn on the first load, preferably the largest load you have.
3. Permit the generator output to stabilize (engine runs smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.
NEVER add more loads than the generator capacity.
Take special care to consider surge loads in generator capacity, as described above.

General Recommendations
Regular maintenance will improve the performance and extend the life of the generator. See any authorized Briggs & Stratton dealer for service.
The generator’s warranty does not cover items that have been subjected to operator abuse or negligence.
To receive full value from the warranty, the operator must maintain the generator as instructed in this manual.
Some adjustments will need to be made periodically to properly maintain your generator.
All service and adjustments should be made at least once each season. Follow the requirements in the Maintenance Schedule chart above.
NOTE: Once a year you should clean or replace the spark plug and replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.
Emissions Control
Maintenance, replacement, or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or
individual. See Emissions Control System Warranty in the Warranties section.
Maintenance
Maintenance Schedule
Follow the hourly or calendar intervals, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.
1Change oil after the first (5) operating hours and every 50 hours or every year, whichever occurs first, thereafter. Change oil sooner when operating under dirty or dusty conditions.
2Replace more often under dirty or dusty conditions.

Generator Maintenance
Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture, or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves, or any other foreign material.
NOTE: DO NOT use water or other liquids to clean generator. Liquids can enter engine fuel system, causing poor performance and/or failure to occur. In addition, if liquid enters generator through cooling air slots, some of the liquid will be retained in voids and cracks of the rotor and stator winding insulation.
Liquid and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.
Cleaning
Daily or before use, look around and underneath the generator for signs of oil or fuel leaks. Clean
accumulated debris from inside and outside the generator. Keep the linkage, spring and other engine controls clean. Keep the area around and behind the muffler free from any combustible debris. Inspect cooling air slots and openings on generator. These openings must be kept clean and unobstructed.
Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris:
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft bristle brush to loosen caked on dirt or oil.
• Use a vacuum cleaner to pick up loose dirt and debris.

NOTE: When adding oil to the engine crankcase, use a high quality detergent oil classified “For Service SF, SG, SH, SJ” or higher. DO NOT use special additives.
1. Choose a viscosity according to the table below.
* Check oil level frequently at higher temperatures.
NOTE: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol with “SJ/CF ENERGY CONSERVING” or higher, is an acceptable oil at all temperatures. Use of synthetic oil does not alter required oil change intervals.
When adjusting or making repairs to your generator:
• Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.
When testing for engine spark:
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
Unintentional sparking can result in fire or electric shock.
WARNING
• DO NOT expose generator to excessive moisture, dust, dirt, or corrosive vapors.
• DO NOT insert any objects through cooling slots.
Improper treatment of generator can damage it and shorten its life.
NOTICE
SAE 30: 40 °F and higher (5 °C and higher) is good for all purpose use above 40°F, use below 40°F will cause hard starting.
10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying temperature conditions. This viscosity improves cold weather starting, but may increase oil consumption above 80ºF (27ºC).
Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides the best protection at all temperatures as well as improved starting with less oil consumption.
5W-30: 40 °F and below (5 °C and below) is recommended for winter use, and works best in cold conditions.
Checking Oil Level
Oil level should be checked prior to each use or at least every 5 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in Checking Oil Level.
3. If needed, slowly pour oil into oil fill opening to the point of overflowing at oil fill.
4. Replace and tighten oil fill cap.
Changing Engine Oil
Change the oil after the first 5 hours of operation.
Change oil every 50 hours thereafter. If you are using your generator under extremely dirty or dusty
conditions, or in extremely hot weather, change the oil more often.
KEEP OUT OF REACH OF CHILDREN.
DON’T POLLUTE. CONSERVE
RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from running, as follows:
1. Make sure unit is on a level surface.

Storage
The generator should be started at least once every seven days and allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following guidelines to prepare it for storage.
Generator Storage
• Clean the generator as outlined in Cleaning in the Maintenance section.
• Check that cooling air slots and openings on generator are open and unobstructed.
Long Term Storage Instructions
Fuel will become stale when stored over 30 days.
Stale fuel causes acids and gum deposits to form in the fuel system or on essential carburetor parts. Prior to storage, if gasoline has not been treated with a fuel stabilizer, it must be drained from the engine into an approved container. Then run engine until it stops from lack of fuel.
When fuel stabilizers are used according to their instructions, there is no need to drain the gasoline from the engine prior to storage. Use Briggs &
Stratton FRESH START™ fuel stabilizer, available as a liquid additive or a drip concentrated liquid cartridge.
Run the engine for a short time to circulate stabilizer throughout the fuel system. Engine and fuel can then be stored up to 24 months.
If gasoline is drained, the use of a fuel stabilizer in the storage container is still recommended to maintain freshness.
Change Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade.
Oil Cylinder Bore
• Remove spark plug and pour about 1/2 ounce (15 ml) of clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly to distribute oil.
Other Storage Tips:
1. DO NOT store fuel from one season to another unless it has been treated as described in Long Term Storage Instructions.
2. Replace fuel container if it starts to rust. Rust and / or dirt in fuel can cause problems if it’s used with this unit.
3. Cover unit with a suitable protective cover that does not retain moisture.
4. Store generator in clean, dry area.
• DO NOT place a storage cover over a hot generator.
• Let equipment cool for a sufficient time before placing the cover on the equipment.
Storage covers can be flammable.
WARNING
When adding or draining fuel:
• Turn generator OFF and let it cool at least 2 minutes before removing fuel cap. Loosen cap slowly to relieve pressure in tank.
• Fill or drain fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• If fuel spills, wait until it evaporates before starting engine.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition sources.
• DO NOT light a cigarette or smoke.
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
WARNING
• NEVER crank engine with spark plug removed.
Unintentional sparking can result in fire or electric shock.

Engine Technical Information
This is a single cylinder, overhead valve(OHV), air cooled engine. It is a low emissions engine.
In the State of California, Model Series 200000 engines are certified by the California Air Resources Board to meet emissions standards for 250 hours.
Such certification does not grant the purchaser, owner or operator of this engine any additional warranties with respect to the performance or operational life of this engine. The engine is warranted solely according to the product and emissions warranties stated elsewhere in this manual.
Power Ratings
* The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05).
Actual gross engine power may be lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given both the wide array of products on which engines are placed, and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site” or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.

Emissions Durability Period and Air Index Information On Your Engine Emissions Label
Engines that are certified to meet the California Air Resources Board (CARB) Tier 2 Emission Standards must display information regarding the Emissions Durability Period and Air Index. The engine
manufacturer makes this information available to the consumer on emission labels.
The Emissions Durability Period describes the number of hours of actual running time for which the engine is certified to be emissions compliant,
assuming proper maintenance in accordance with the Maintenance Schedule. The following categories are used:
Moderate: Engine is certified to be emission compliant for 125 hours of actual engine running time.
Intermediate: Engine is certified to be emission compliant for 250 hours of actual engine running time.
Extended: Engine is certified to be emission compliant for 500 hours of actual engine running time.
For example, a typical walk-behind lawn mower is used 20 to 25 hours per year. Therefore, the Emissions Durability Period of an engine with an intermediate rating would equate to 10 to 12 years.
The Air Index is a calculated number describing the relative level of emissions for a specific engine family.
The lower the Air Index, the cleaner the engine. This information is displayed in graphical form on the emissions label.
Emissions Compliance Period On Engine Emissions Compliance Label
After July 1, 2000 certain Briggs & Stratton engines will be certified to meet the United States
Environmental Protection Agency (USEPA) Phase 2 emission standards. For phase 2 certified engines, the Emissions Compliance Period referred to on the Emissions Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emission requirements. For engines less than 225 cc displacement, Category C = 125 hours, B = 250 hours and A = 500 hours. For engines of 225 cc or more, Category C = 250 hours, B = 500 hours and A = 1000 hours.
This generator engine has an intermediate rating with an Air Index of 3. The EPA Emissions compliance period is Category C. The displacement of this engine is 305 cc.
Below is a generic representation of the emission label typically found on a certified engine.
